If they have the source code and someone capable of running it, fixing this issue will be only a matter of seconds and then releasing a new binary. It is very disappointing that every single response we have from Devialet proves that the Expert line is dead. I was planning to buy a second 220 (and Devialet is well aware of it as we had an open topic for it with the support team) but as seeing this topic, I have changed my mind and going to look into Benchmark Dac+Pre+Power combo.
